"Is it safe to continue driving with low coolant as long as I continue to watch the temperature gauge? " No, the temp sensor reads coolant temperature, if the coolant gets low enough to be below the temp sensor, now the sensor is reading metal temperature of the area it is screwed into (usually cylinder head), by the time it reads too hot on the gauge the ...

If you do not have any leaks, then your coolant is most likely getting burned and/or going into your oil. My guess is going to be a problem with your head gasket or some crack or warping in the head. I believe coolant in oil used to turn oil more brown and make it more foamy or milky. These days, the detergents and dispersants in modern oil can reduce ...

First, you do need to find out where the coolant is going. There is UV dye that can help with this, and if your car is smoking, that could be a sign that the coolant is leaking into the engine rather than on the ground. For the main question, "Is it safe", as long as you keep an eye on the temperature and it's not getting too high, you should be OK in the ...

If it has an engine oil cooler, that is most likely the problem, a faulty oil cooler, some are made into the radiator, others have heater hoses running to a remote oil cooler, and a few I have seen are where the oil filter screws on, the oil cooler has a leak into the coolant side. The reason no coolant is in the oil is because it is a high pressure leak, ...

Its not good to run with low coolant, even worse to run with no coolant. Actually it can be quite disastrous (possibilities include blown head gaskets, seized pistons and a number of expensive repairs), but many times this is a result of a leaky radiator cap which is easy (and cheap) to replace. Someone already mentioned the dyes for detecting leaks, but ...

If you can't see any obvious signs of leaks, or steam coming from anywhere if you run the engine, a likely cause is a cracked cylinder head gasket, which is letting the coolant into the cylinders and out of the tail pipe as steam. That could soon cause a lot more damage than the hassle carrying a water container in the car to top up the radiator. Personal ...

Clear water is not a sign of requiring a flush. It might be a sign that you need some anti-freeze... Brownish water or any other color that is not the normal color of your coolant could potentially benefit from a flush. Plain water in our engine could potentially cause problems: Water will boil over and not cool the engine sufficiently. Danger of rust if ...
